Firmware Update Using Multiple Gateways in LoRaWAN Networks.

The remarkable evolution of the IoT raised the need for an efficient way to update the device's firmware. Recently, a new process was released summarizing the steps for firmware updates over the air (FUOTA) on top of the LoRaWAN protocol. The FUOTA process needs to be completed quickly to reduce the systems' interruption and, at the same time, to update the maximum number of devices with the lowest power consumption.
